I have always purchased phones in the store. However to take advantage of the $30 promo code I am trying to order online. However, I do not see where it offers me the option to "upgrade" as I am going to be using my NE2 $100 credit. Towards the end of the online purchase it only asks me if I would like a new number or if I am transferring from another service. What am I doing wrong? Thanks for any help!!!
